摘要: 塔河油田12 区奥陶系缝洞型碳酸盐岩储层,储集空间结构复杂多变,孔、洞、缝发育,具有很强的非均质性。在塔河地区奥陶系发育许多测井响应特征与真储层相似,试油却为干层的假储层。如果不对这些假储层加以分析剔除,就很难准确地进行储层识别,从而造成测井解释错误,并给后续的试油和生产造成直接经济损失。因此,如何应用测井资料鉴别真假储层成为塔河地区储层测井评价的关键。通过研究总结了塔河12 区真假储层的测井响应特征,并利用常规测井、成像测井和岩芯资料等建立了该区常见真假储层识别模式,减少漏划错划储层现象,提高储层测井评价的精度。

Abstract: The fracture and cave reservoir of Ordovician formation in area 12 in Tahe Oilfield has a strong heterogeneity,and
complex spatial structure of reservoir which highly develops pores,holes,and fracture is developed is complex. There are many
layers which have the similar characteristics of reservoir in the Ordovician formation in Tahe Oilfield,but they turn out to be
the false reservoir for the test oil is dry layers. If these false reservoirs are not analyzed and removed,it is difficult to accurately
identify the reservoir. What’s more,it will cause the erroneous interpretation of well logging and the direct economic losses of
oil test and production. Thus,how to identify true or false reservoir with log data becomes the key of reservoir evaluation in
Tahe Oilfield. In this paper,we sum up the log response characteristics of true and false reservoir in area 12 in Tahe Oilfield,
and establish the identified patterns of true or false carbonate reservoir with well logging,FMI and core data,which reduces
the wrong and omission reservoir identification to improve the accuracy of reservoir logging evaluation.

Key words: carbonate rock, log response characteristics, true or false reservoir, reservoir identification
